Note Most USB and IEEE devices function correctly without additional device drivers because they are configured by the drivers that are included with Windows for these bus types. However, an additional device driver is needed if the device does not fit the defined and supplied Windows class drivers.

If the bus cannot identify the device, it interprets the device as a composite device and then reports it as such in Device Manager.

This article describes how to manage stored user names and passwords on a computer that is not a member of a domain. When you log on to a Windows XP-based computer, you can supply a user name and password, which becomes your default security context for connecting to other computers on networks and over the Internet.

However, this user name and password may not provide access to all desired resources. The Stored User Names and Passwords feature provides a way to store additional user names and passwords as a part of your profile. Stored User Names and Passwords is a secured store for password information. With this feature, you can type user names and passwords for various network resources and applications such as email one time, and then have Windows automatically supply that information for subsequent visits to those resources without your intervention.

When you first log on to a server or a Web site, you are prompted for your user name and password. When you type your user name and password for the resource, and then click to select the Remember my password check box, your logon information is stored with your user account. When you next connect to the same resource, these stored credentials are used by Windows to automatically authenticate your user account.

When a credential is saved by selecting the Remember my password check box on the user name and password dialog box that you receive when you connect to a resource, the credential are saved in the most general form possible. Saving a different credential for a different server in this domain would not overwrite this credential.

The new credential would be saved by the use of more specific information. When you access a resource, the authentication package searches the Stored User Names and Passwords store for the most specific credential that matches that resource. Reply to author.

I had a program installed on my computer which required a serial key. I recently formatted my hard drive, and now the program is recognizing that I already installed the software on a computer with windows system id "my old system id".

I am wondering how I can change my current system id to match the old one the software is listing. I have been told to change my computer name throught "my computer, properties, computer name" but that is not it. If that's not possible, you won't be able to use the command prompt for changing the computer name. N ow that you have a more friendlier computer name, it will make connecting computers together on your home network much easier to identify. Click here to cancel reply.
